Re: copy from flash to ram

Pierre,

With Intel StrataFlash you can do either. You can have your image
boot in XIP in flash or Copy the image into RAM and execute there. It
all depends on the bootup speed, execution speed, DRAM space, Flash
space you are looking for.
Image being XIP in flash: It will be faster to start booting by
slower to execute and will take its image size out of flash.
Image being in DRAM: It will take long to start booting (time to copy
image into RAM), but faster to execute, but it will take its image
size out of DRAM .

If you are having problems with flash execution, post your config.bib
file here and what processor you are using.
Also, check if you have XIP (IMGFLASH) enabled in the PB settings for
the build ( Platform->settings->Build Options & enable "Write Runtime
Image to Flash Memory")

Hey

i have problem to startup the runtime image from flash and in ram
works everything fine. So is possible to copy the runtime image first
to ram before executing. I'm using Intel StrataFlash memory. and P.B
5.0. And if this is possible, whats the easiest way to do this?

thanks
Pierre
